Chevrolet 3-Pin DRL & Excavator Throttle Switch Connector – OEM 15326614 / 15326626 / P1350600
Direct OEM-specification replacement for the 3-pin connector used on Chevrolet daytime running light (DRL) modules and excavator throttle switch harnesses. Cross-references OEM part numbers 15326614, 15326626, and P1350600. This connector serves dual-market applications: automotive DRL control modules on Chevrolet platforms, and throttle position switches on construction equipment (excavators, loaders). Available bare or with 15cm pre-wired leads.
The same 3-pin connector housing is used in two distinct markets due to identical terminal pitch and housing geometry:
| Market | Application | Typical Failure Symptom |
|---|---|---|
| Automotive (Chevrolet) | DRL module control harness | DRL not illuminating, DRL warning light on dashboard |
| Construction Equipment | Excavator throttle position switch harness | Engine not responding to throttle input, idle-only operation |
| Pin | Function (DRL Module) | Function (Throttle Switch) | Failure Symptom if Corroded |
|---|---|---|---|
| 1 | +12V power to DRL module | +5V or +12V reference to throttle switch | DRL module inactive / throttle switch not reading |
| 2 | DRL control signal from BCM | Throttle position signal output | DRL not responding to BCM / engine not responding to throttle |
| 3 | Ground / DRL module earth | Signal ground / return | DRL flickering / erratic throttle reading |
| Attribute | Detail |

Q: My Chevrolet DRL warning light is on but the headlights work fine — is it the connector?
A: A DRL warning light with functional headlights indicates the BCM has lost communication with the DRL module. A corroded 3-pin DRL connector is a common cause before the DRL module itself fails. Inspect the connector before replacing the DRL module.
Q: My excavator engine only runs at idle and won’t respond to the throttle lever — is it the connector?
A: Idle-only operation on an excavator with a non-responsive throttle lever is frequently caused by a corroded throttle position switch connector rather than a failed throttle lever or ECM. The ECM defaults to idle when it loses the throttle signal. Inspect the 3-pin connector before replacing the throttle switch assembly.
Q: Are terminals included?
A: Yes, terminals are included with all variants.
